CVE-2026-71944 is a critical OS command injection vulnerability in D-Link DWR-M961 routers, hardware version C1, running firmware versions prior to 1.1.5_C1_202607071108. The flaw is present in the web management interface endpoint /boafrm/formLtefotaUpgradeQuectel, where insufficient sanitization of the fota_url parameter allows attacker-controlled input to be interpreted as shell commands. A remote attacker can exploit the issue without authentication by submitting crafted input to that field, leading to arbitrary command execution in the underlying operating system context. The injected commands execute with root privileges on the device.
